In this study, the method for improving the mold transcription on casting was proposed after several water simulation. Two kinds of vessels made from acrylic resin were prepared as a crucible. One had a nozzle of 7mm in diameter (single nozzle). Another had two nozzles of 2mm and 3mm in diameter (double nozzle). Water in the vessel flowed onto a mold made from acrylic resin with a minute hole. The volume of the water in the vessel was 2ml, 3ml and 4ml. The hole diameter of the mold was 2mm, 3mm and 4mm, and hole depth was 2mm, 3mm, 4mm and 5mm. When the vessel with single nozzle and with double nozzles was used, the filling ratio decreased as the hole depth of the mold increased. The filling ratio increased as the whole diameter of the mold decreased. The volume of water had no effect on the filling ratio. The filling ratio was improved due to the vessel with double nozzles. These results show that mechanism of filling the minute hole of the mold was clarified in this study.
